I've just gotten a bug report (#219584) which points me to /usr/share/doc/libc6/FAQ.gz. Nice, except that the FAQ doesn't tell me anything - presumably since I'm not running unstable (for good reason, apparently).
Might I suggest that this error message (and anything similar) point to a web version of the FAQ or some other appropriate page? Save some hassle for all the poor people who would otherwise have to contrive to unpack the unstable glibc? - Matt
